- 2 tablespoons dry mustard powder (sold in the department of La Spezia) diluted with hot water
- 2 tablespoons hot water
- 1 egg yolk
- 2 tablespoons olive (peach, burdock and any other cosmetic oils)
* 2 teaspoons of sugar (greater than sugar, the "meaner" mustard) must wait for 15 minutes to 1 hour, depending on how much "was hot." If tolerated, it is best to look like as 1:00, dreaming of a luxurious long spit. And if you really "fire" on the head, it is only 15-20 minutes.

Warning! 15 minutes have to sit out the first time be sure, even if it seems that on the head there was a nuclear war. 15 minutes no harm your scalp and hair will not (tested many), and used to it, you then half an hour and an hour after sitting.
